History The DOHC HEMI

I found one photo on the net and it led to this article from hot rod https://www.hotrod.com/articles/return-dohc-426-hemi/

Most of the following photos from there but some from the web.

Read the Hot Rod article it's very interesting. I had never heard of this before

It was rumored about in 1964 and a couple were made for NASCAR but then disappeared. And now one has been found.

Some of the photos get LARGE

Something to counter Fords 427 SOHC, if it would have been allowed to run in the grand national series.

 

Uncle Tony on youtube has a great video about the OHC V8's in the late 60's by the big 3.
Very interesting. Especially Pontiac.

 

That is exactly why they were made. It's in the article

 

...some wild R&D in the 60s......
Let us give thanks to all of the nay-sayers and bean counters for squashing them.

Awesome Era! Seems like every issue of Hot Rod had factory experimental engines on the cover. Did I Buy them?! Yes, Sir.

 

MURICA! Because we can, because too much is still not enough. Awesome engine. Thanks for posting.

 

And if you are into models, the 1/25th scale AMT 1970 Dodge Coronet Pro Street kit has the DOHC Hemi as an optional build.......the DOHC stuff is only in the Pro Street kit, not the stock 1970 Coronet kit and is in every reissue of the Pro Street kit......andyd

 

But it's not a real Hemi:

 

I also have a couple of those....

 

Awesome piece of Mopar history, thanks to everyone that posted photos and links...

 

Looks like in this one they are checking cam twist.

 

& then there's the Aug '57 MOTOR TREND cover pic n 1pg article(p 42) on "Chrysler 500hp 4-cam v8", w/4 carbs(97's?). Based on on a '53 hemi, '55 heads - modified for 2 cams each. 7k rpm. Gear drive to the intake cams, exh cams run w/chain from int cams. Was going to all gear drive. Builders' name was Bill(Bob) Gillelan. Was 10 month long project at article time. Looks like he worked in Moldex Tool Shop in Detroit, & balancing was done by Leo's Custom Racing Engines. No pics due to my trouble w/posting pics/scans. Sorry.
Marcus...

Interesting that they opted for belt driven cams, as opposed to Ford's SOHC.

 

I read in the past that this motor couldn't run under it's own power.... Not sure if it's true or not..... More info needed please...... Inquiring minds like mine would love to know!!!!...

 

Did you read the article in the link it has a lot more history on it?

 

No I didn't....
Maybe I should..... Duh!

 

- I can only read pictures - Ha!
